I'm still working on that platformer but I encountered another small issue regarding the sprites. I'm trying to cut out sprites from a spritesheet but once I do, these ugly borders persist around the sprite( I'm using a colorkey to remove the background colour ). My plan was just to, instead of using the color: 0, 0xFF, 0xFF as sprite background, to use a simple alpha instead of a background colour, therefor removing said ugly borders. My main problem is, that if I try to use a PNG ( using SDL_image for this ) with a transparent background, it doesn't show any kind of transparency once I load it in. Just a black box around said sprite.
